pylint 和 astroid AttributeError：“模块”对象没有属性“col_offset”

Question

使用pylint 版本2.9.0 和2.9.3 失败。使用 2.8.3 版本时，它仍然可以工作。

该测试环境的requirements.txt - 文件包含：

astroid
src/packages/project/requirements.txt
pycodestyle
pylint
pylint_junit
pytest
pytest-cov
yapf

src/packages/project/requirements.txt 包含：

awswrangler==2.8.0
babel==2.9.1
boto3==1.17.77
botocore==1.20.77
category-encoders==2.2.2
joblib==1.0.1
markdown==3.3.4
matplotlib==3.3.4
openpyxl==3.0.7
pandas==1.1.5
pyarrow==4.0.0
pytz==2021.1
requests==2.25.1
scikit-learn==0.24.2
simple_salesforce==1.0.0

对产生相同错误的不同尝试进行编辑：

1. 正在安装pylint=2.9.3
2. 安装astroid 和pylint（最新版本，无版本说明）
3. 安装astroid 和pylint 并在构建过程中通过pip install --upgrade astroid 将astroid 升级到最新版本（在AWS test-buildspec.yml 中）（建议here）

Answer 1

看起来你在 pylint 2.9 中发现了一个错误/崩溃，你可以打开一个问题 here。您可以在修复时降级到 2.8.3。

Answer 2

感谢@Pierre.Sassoulas 的工作，此问题已得到解决（请参阅here）。

在证明pylint - 和 astroid - 的以下组合可以很好地协同工作而不会产生 OP 错误后，已对 GitHub-project 进行了新的提交以解决该问题：

pip install pylint==2.9.3
pip install git+git://github.com/PyCQA/astroid.git@c37b6fd47b62486fd6cbe77b913b568b809f1a6d#egg=astroid

从这里开始，在安装最新版本的 pylint 和 astroid 时不会再出现该问题。但是，如果问题再次出现，我会在这里通知您。
